Bought the sterilizer to help control a cyanobacteria outbreak in my reef tank. Within two days the water went from almost opaque to crystal clear, and my corals and fish look better than they ever did. Can't recommend this enough!

I had been thinking about getting a UV sterilizer for a while for my tank. I’d had algae bloom issues off and on for about a year. The latest one just would NOT go away. I tried everything I could, including frequent small water changes and blacking out the tank, but I couldn’t get rid of the green water that had become so thick that I could barely see the fish, let alone anything else in the tank. 48 hours after setting up the sterilizer, my water is crystal clear. The tank looks better than it ever has, and I’m sure the fish are breathing easier, too. So far, I’m very happy with it. Just make sure that you’re aware that this sterilizer will need a pump, since it doesn’t have one built in, and you’ll need the appropriate sized tubing. It’s not difficult to set up, and it works well.

This was an exact replacement on my 135 gal freshwater tank. Had recurring leak troubles with the current turbo-twist and was really aggravated with it, but also

This was an exact replacement on my 135 gal freshwater tank. Had recurring leak troubles with the current turbo-twist and was really aggravated with it, but also realized how many years I had run it. In the end went with this again as it does work great if you are lucky enough to avoid the niggling leaks. Chewy new to me but great to deal with.
